Direct metallation of 2-hydroxyphthalocyanine J-type slipped-cofacial dimeric ligand by Mg, Zn, Cu, Ni and Co salts has been carried out to obtain corresponding metal complexes selectively without any noticeable dissociation or polymerization of the starting ligand. Integrated analysis of aggregation properties in the synthesized series has been conducted with the involvement of AFM microscopy, UV/Vis spectroscopy and theoretical assessment. As a result, a nonlinear relationship between absorption and concentration was found, with aggregation beginning to appear at concentrations above 3.3 × 10 mol L with predominant formation of trimers from the dimeric molecules in THF solutions.
通过镁、锌、铜、镍和钴盐对 2-羟基酞菁 J 型滑面二聚体配体进行直接金属化，在不明显解离或聚合起始配体的情况下选择性地获得相应的金属配合物。通过原子力显微镜显微镜、紫外/可见光谱和理论评估对合成系列的聚集性质进行了综合分析。结果发现，吸收与浓度之间存在非线性关系，在浓度高于 3.3×10-5 mol·L-1时开始出现聚集，在四氢呋喃溶液中二聚体分子主要形成三聚体。
